I am working on a Windows Forms based .Net application that uses SQL 2008 database as back-end. We have a few search screens that allow the user to enter search criteria. Some queries take a lot of time to execute while most of the queries take only a few seconds. Is there a way to prevent a query from being fired if the cost of the query is expected or calculated to be very high?I'd like to display a warning message to the user that the query would potentially run for a while. The user should given the choice of refining the query or agree to wait several seconds.<br />
<br />
We are using select top 100 is the queries but is there a different solution that would warn the user before firing the query?<br />
